monitor/display problem.

Good afternoon,

A short while ago, I did my weekly patches (dnf upgrade), and then 
re-booted.  Just before that, the workstation display (dual monitor) was 
fine.  After the reboot, only one display works. If I switch the monitor 
cables, I still get a one-monitor display, but on the other monitor.  
This leads me to think that the problem is not with the monitors.  The 
display in the one monitor looks a little fuzzy and stretched out 
horizontally.  I also notice at the end of the boot log the following lines:
-----
M
[    **] (2 of 3) Job plymouth-quit-wait.ser…tart 
running (1min 17s / no limit)
M
[   ***] (2 of 3) Job 
plymouth-quit-wait.ser…tart running (1min 17s / no limit)

M
[ ***  ] (3 of 3) Job 
akmods.service/start running (1min 18s / no limit)

from akmod packages.

[  OK  ] Started gdm.service - GNOME Display 
Manager.

(first and last lines are for context only)
I can't memorize fast enough, but I did notice during the last boot 
lines very much like (or identical to?) the lines above that mentioned 
"nvidia".

What is the problem?
More important, how do I fix it?

thanks,
Bill.
